To all 'whom 'it may concern: I

Be it known that I, JOHN H. RIGBY', a citizen of the United States, residing at Lynn, in the county of Essex and Stateof Massachusetts, have invented certain new and useful I m rovements in Sole-Leveling Maf chinos an I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will4 enable others skilled in the artto which it appertains to make and use the same.

The present invention relates to sole leveling rolls for use in sole leveling machines and particularly to sole leveling rolls adapted to operate u on turned shoes. 4

To level t e sole of a turned Vshoe itis necessary to subject the sole to both a rubbing and a pounding or-'beatin action. Vhen the leveling operation has een performed by a machlne this rubbing and pounding action has usually been secured by means o a rotating leveling roll, the surface of which is interrllrpted so as to form a series of projections. o provide an interrupted surface, the roll has been made in various Ways as for instance by providing the roll with slots or by forming the surface of the roll by a series of suitabl arranged small rolls.- In every instance, ovvever, the sole poundin or beating ribs orprojections have extende entirely across the roll so that the central portionv as V,Well as the end portions act to vbeat out theV sole. The entire surface of the sole of a shoe is thus subjected to the beating or pounding action of the ribs of the roll and as a consequence the sole is liable to be stretched longitudinally especially if the roll is pressed against the shoe With a heavy pressure. Accordingly, y considerable care must be exercised by the operator, and because a heavy pressure cannot be applied to. the sole, the shoe' must be gone over a num# ber of timesand considerable time consumed before the sole 'is brought into the desired condition.

The object of the present invention is to provide a sole leveling roll which can be used to level the sole of a 'turned shoe with less liability of stretchin the lsole longitudinally with greater pressure Without liability of injuring the so e so that a superior quality of v work can be produced and the amount of time required for the leveling operation can be substantially reduced.

ich can-be orced against the shoe` With the above object in view the present sole leveling roll, t e central portion of which is provided with a smooth sole rubbin surface and the end portions only of Whic are provided with sole beating rojeotions. lThe central smooth portion of t 's roll bears upon the central portion of the shoe sole during the leveling operation and acts efliciently to smooth out the sole in a satisfactory manner, the character of this portion of the sole being such that it can be satisfactorily leveled Without bein subjected to any beating out Operation. e end portions of the roll en age the edges of the shoe sole and since these end portions are rovided with sole beating projections thee ge portions of the sole are subjected to the neoessar beating out action, and the entire sole is eveled in a satisfactory manner. By reason of the factthat the central smooth portion ofthe roll does not act aplpreciably to stretch the sole, the leveling ro the sole with a much greater pressure than has, heretofore been possible and consecan be pressed against quently the sole can be leveled ina much more satisfactory manner and in a much shorter sipace of vtime than when `a roll is employe in which the sole beating projections extend the entire length of the roll."

formed by interrupting the surface of the rollI by means of slots iwhich are the same Width throughout their length, as thereby projections are formed Wluch have substantially the same beating out vaction throughout their length and which present Wide surfaces to support the roll in contact With the shoe and revent the projections from sinkin Vtoo dee ly/into the surface of the'sole. lso, pre erably, the projections extend obliquely to the axls of the roll and the projections at each end of the roll converge toward each other so that the projections exert an outward wiping action on the sole. A

The present invention Will vbe clearly understood from an ins ection of the accompanying drawing in W 'ch- Figure 1 is a view in side elevation of a roll embodying the same in its referred form, and Fig. 2 is a view of the roll 1 lustrating one half of the roll inend elevation and the other ha'lf in section on the line 2--2- of Fig. l1.

The roll illustrated in the drawing is of substantiall the same shape as rolls which 4 the sole beating projections are indicated at 2. These pro ections, as indicated in the drawing,` are` ormed by slots 3 cut in the end surfaces of the roll and extendin diagonally to the axisyof the roll. the projections 2 are slightly rounded oi, as best shown in Fig. 2, to prevent injury to the sole as these edges strike -the sole during the rotation of the roll. As indicated in Fig. 1,

'the slots 3, at op osite ends of the roll converge toward eac other and it will be apparent from an inspection of the figure, that this arrangement of the slots causes the projections 2 to exert an outward wi ing action on the sole of a'shoe acted u on y the roll.

r vention havi ferred form-o vthe lnvention having been The slots 3 are of a Width su the'projections to deliver blows ofthe desired force upon the sole.

The manner in which the roll acts u on a shoe sole and the advantages secured y its use will be obvious to those skilled in the art Without further description.

The nature and scope of the present inbeen indicated and a prespecificall described, what is claimed is -1. A vso e leveling roll provided at its cen- The e ges ofcientto cause ter with a smooth sole rubbing surface and at its ends with a series of sole beating projections.

2. A sole leveling roll provided at its center with a smooth sole rubbing surface and at its ends with a series of sole beating rojections arranged obliquely to the axis o the roll and adapted to exert an outward wiping action 'on the sole of 'a shoe.

, 3. A sole leveli 0 roll provided at its centerwith a smooth so e rubbing surface and having its end surfaces interrupted by a series of slots dividing said surfaces into a series of sole beating and rubbing projections.

. 4. A sole leveling roll provided at its center with a smooth rubbing surface and having its end surfaces interrupted by a series of slots extending obliquely to the axis of the roll and dividi said surfaces into a series of sole beating an rubbing projections adapted to exert an outward wiplng action upon the sole of a shoe.

5. A sole leveling lroll provided at its center with a smooth sole rubbing surface and have i ing its end surfaces interrupted by a series of slots of the samewidth throughout theirv length, and dividing each of said surfaces into a series of. sole beating and rubbi rojections, the slots at opposite ends o t e roll converging toward each other and 'being arrangted cbliquely to the axis of the roll y where y the projections exert an outward Wi ing action upon the sole of a shoe.
